1^ to 2 inches long ; bracts lanceolate, acuminate, pubescent, nearly 

 equalling the villous calyx : calyx-teeth very villous, broad at base, 

 acuminate, as long as the turbinate tube ; petals dark purple, 3 lines 

 long. — Collected by Seemann in the Siei-ra Madre, probalily in Du- 

 rango, and by C. R. Orcutt at Socouo, in Lower California, April, 

 188G. 



Astragalus Hendeksoni. Thinly pubescent throughout with 

 soft woolly hairs, the numerous stems erect or ascending from a stout 

 rootstock, 1 to 2 feet high: leaflets 6 to 10 pairs, narrowly oblong, 

 obtuse or retuse, 6 to 9 lines long ; stipules lanceolate : pedunculate 

 racemes exceeding the leaves, few-flowered : calyx tubular-campanu- 

 late, dark-villous, 3 or 4 lines long, the narrow teeth nearly equalling 

 the tube: pods reflexed, 2-celIed, very fleshy-coriaceous, upon a stipe 

 twice longer than the calyx, turgid, oblong to oblong-obovate, with a 

 stout prominent.ventral suture, the dorsal less prominent, very abruptly 

 mucronate, glabrous, rugose, 8 to 11 lines long by 4 thick. — Open 

 hillsides in the foothills of the Siskiyou Mountains, Josephine County, 

 Oregon (L. F. Henderson, July, 1886). A very peculiar species, with 

 the strictly 2-celled fruit nearly as fleshy as in the Scytocarpi, but 

 dehiscent, stipitate, and reflexed. 



Astragalus accidens. Rather stout, sparingly pubescent, the 

 numerous stems a foot long or more: leaflets 10 to 15 pairs, oblong, 

 retuse, cuneate at base, glabrous above, appressed-pubescent beneath, 

 6 or 8 lines long on a rhachis 3 to G inches long : jjeduncles about 

 equalling the leaves, bearing a short raceme : flowers reflexed ; calyx 

 campanulate, dark-pubescent, 3 lines long, the teeth nearly equalling 

 the tube ; corolla yellowish, the narrow erect banner 6 or 7 lines 

 long : ovary white-pubescent ; pod 2-celled, stipitate (stipe as long 

 as the calyx), coriaceous, turgid, oblong-ovate, subsulcate on the 

 back, the ventral suture somewhat prominent, straight, reflexed, 

 pubescent, 4 or 5 lines long. — Southern Oregon (T. J. Howell, 

 April, 1881). Pod approaching that of A. llortoni, hut usually more 

 compressed and broader, stipitate, and reflexed. Most nearly allied 

 to the last. 



Astragalus (Eriocarpi) lectulus. Dwarf, closely cespitose, 

 prostrate, densely silky-tomentose ; stems very short : leaves an inch 

 long, with 2 to 4 pairs of oblong-elliptical or oblanceolate leaflets 

 2 or 3 lines long: raceme shorter than the leaves, few-flowered, and 

 very shortly pedunculate: calyx tubular, pubescent with soft wliite 

 hairs, 3 lines long including the short narrow teeth ; corolla purplisli, 

 4 to G lines long: pods densely hairy, 6 lines long, compressed-ellipti-
